Problems solved by technology

Even in the disconnected state, however, the torque-transmitting components of the connectable drive shaft rotate together, which leads to undesired power losses (Verlustleistung)
This loss of power results in a multi-axle motor vehicle with a waiting drive train having a higher fuel consumption than a single-axle motor vehicle

Embodiment Construction

[0029] Figures 1 to 5 In view of their commonality, they are firstly described together. A drive unit 2 for a multi-shaft drive motor vehicle 3 is shown schematically. From motor vehicle 3 , a drive unit 4 , a first drive train 5 for driving a first drive shaft 6 and a second drive train 7 for driving a second drive shaft 8 can be discerned. The drive unit 4 includes an internal combustion engine 11 , a coupling 9 and a transmission 10 via which torque is introduced into the first and second drive train 5 , 7 . It is understandable that the drive unit can also be any other drive, such as a motor.

[0030] In order to distribute the torque generated by the drive unit to the first drive train 5 and the second drive train 7 , a splitter transmission 12 is provided. The splitter transmission 12 preferably comprises a differential transmission 58 having an input part 17 and three output parts 20 , 21 , 31 which have a balancing effect on one another. The input part 17 of the d...

Abstract

The invention relates to a drive arrangement for a multi-axle driven motor vehicle having a drive unit. The drive arrangement comprises a distributor gearbox 12 distributing the torque induced by the drive unit 4 to a first drivetrain 5 and a second drivetrain 7, wherein the first drivetrain 5 is continuously drivingly connected to the distribution gearbox 12 in order to transfer torque to a first drive axle 6, and wherein the second drivetrain 7 can be switched to drivingly connect to the distribution gearbox 12 in order to transfer torque to a second drivetrain 8, and a longitudinal driveshaft 24 disposed in the flow of torque between the distribution gearbox 12 and the second drive axle 8; wherein first coupling means 22 are provided for coupling and decoupling the longitudinal driveshaft 24 relative to the drive unit 4 and wherein second coupling means 26 are provided for coupling and decoupling the longitudinal driveshaft 24 relative to the second drive axle 8.

Description

technical field [0001] The invention relates to a drive unit (Antriebsanordnung) for a motor vehicle with a multi-shaft drive. The drive unit comprises a first drive train for continuously driving the first drive shaft and a second drive train which can be switched on if necessary in order to transmit torque to the second drive shaft. Such a drive assembly with an on-demand drive shaft is also referred to as a "hang-on" or "on-demand" system ("hang-on" or "on-demand" system). Background technique [0002] In general, there are differences in the different drive modes in motor vehicles. There are therefore motor vehicles with a front motor in which the front axle is continuously driven and the rear axle is switchable. In addition, there are motor vehicles with a front engine in which the rear axle is continuously driven in reverse and the front axle is switchable. Finally, motor vehicles are known with a rear engine in which the rear axle is continuously driven and the fro...
